Band electron spectrum and thermodynamic properties of the pseudospin-electron model with tunneling splitting of levels

Band electron spectrum and thermodynamic properties of the pseudospin-electron model with tunneling splitting of levels

The pseudospin-electron model with tunneling splitting of levels is considered. Generalization of dynamic mean-field method for systems with correlated hopping was applied to the investigation of the model. Electron spectra, electron concentrations, average values of pseudospins and grand canonica...

description The pseudospin-electron model with tunneling splitting of levels is considered.

Electron spectrum and dependencies of the electron concentrations on chemical potential were obtained. It was shown that in the alloy-analogy approximation, the model possesses the first order phase transition to ferromagnetic state with the change of chemical potential and the second order phase transition with the change of temperature.
